Description

Primary dentition is the most suitable space maintainer for permanent teeth. However, as infants often lose their primary teeth too soon, using a space maintainer is the most efficient, long-lasting, and economical way to prevent malocclusions and function impairment in the future. Regarding personalized appliances, space maintainers in digital pediatric dentistry have made significant progress. Digital technology decreases the manual manufacturing stages that take a long time and increases the reliability and durability of digital fabrication procedures.
